7z files and Scanning Directories

I have some roms in 7z files and when I scan a directory for a playlist it finds nothing but if I scan the file itself it shows up in the playlist and plays fine is this a bug or is it supposed to work this way?

which lakka build date are you on…are your 7z in their own folders?

I’m on the newest and the 7z files are all in one directory, let’s call it SMS.

what is the build date when you say newest? are you playing an arcade game? i don’t recall any system supporting .7z formal
